As one of the world’s top scientists, ProfessorTim Spector’s research has transformed our understanding of food and its profound effect on long-term wellbeing. So we asked him for his advice on what hacks are actually worth digesting and what should be ignored
As one of the world’s leading voices in nutritionand gut health, professor Tim Spector is particularly sceptical of anyone promising that one food, one supplement or one extreme diet will transform your health
“Nutrition has become incredibly noisy, and it’s easy to mistake confidence or popularity for expertise. A person having millions of followers, a great physique or a convincing social media presence doesn’t necessarily mean they understand nutrition science,” explained Professor Spector
“I’ve seen countless trends go viral despite having little evidence behind them. Celery juice, for example, has been touted as a cure-all despite no evidence it can “detox” the body. Greens powders are often marketed as a substitute for eating vegetables, but they can’t replicate the full nutritional benefits of whole plant foods. And colostrum supplements are frequently promoted for supporting recovery and immunity, even though the evidence supporting these claims in human adults remains limited.”
He adds: “Real science is rarely that simple. Instead, look for advice from qualified nutrition scientists, registered dietitians or medical professionals who can explain not only what works, but why it works
How to tell if nutrition advice is actually backed by science
“The same applies to products. Before spending your money, ask whether they have been properly tested. Has the product been studied in a randomised controlled trial – the gold standard for testing whether something genuinely works? Have the results been published in a peer-reviewed scientific journal, allowing other scientists to examine and challenge the findings? Or is the evidence simply based on testimonials, celebrity endorsements or unpublished claims?”
One thing he would encourage men stop doing is chasing the latest nutrition trend they see online
Stop chasing the latest nutrition trend
“Every week, there’s a new “miracle” product, diet, detox drink or pre-workout claiming to unlock better health, more muscle or peak performance – yet many of these trends are built on marketing rather than meaningful science. Most of these trends disappear as quickly as they arrive because they’re not built on evidence
“We are naturally drawn to the idea of a shortcut since it is much more appealing to believe that one food, supplement, or routine will transform your health than to accept that the biggest benefits usually come from relatively simple habits repeated over time
“The good news is that our biology is not fixed – and one of the most overlooked areas is looking after your gut microbiome. AtZOE, we’ve spent years studying the relationship between food, the gut microbiome and long-term health, analysing one of the world’s largest collections of nutrition and microbiome data. What we’ve consistently found is that people with healthier, more diverse gut microbiomes also tend to have better metabolic health. The gut microbiome is also linked to mental health through what’s called the gut-brain axis.
The simple 30-plants-a-week rule
“One of the clearest findings from our research is that diversity matters. The most practical way to support your gut microbes is to eat a wide variety of plants. That does not just mean fruits and vegetables. Beans, lentils, whole grains, nuts, seeds, herbs, and spices all count
“People who eat around 30 different plant foods each week tend to have more diverse gut microbiomes than those who eat only a handful of plants on repeat. That’s because every plant contains its own unique combination of fibres and polyphenols, which nourish different groups of beneficial microbes
“This doesn’t have to be complicated. A bowl of Greek yogurt topped with berries and cinnamon can provide several different plant foods in one meal. A bean chilli packed with mixed vegetables, herbs and spices is another simple way to increase diversity. Small changes, repeated consistently, can have a big impact
“I’d also challenge the idea that men need to obsess over protein at every meal. Protein is important for maintaining muscle, especially as we get older, but most men in the UK already consume enough. The nutrient that is far more commonly lacking is fibre. Around 96% of adults in the UK don’t consume enough fibre, despite it being the primary fuel for our gut microbes. These microbes produce compounds that influence inflammation, immune function and metabolic health – all areas that matter whether you’re lifting weights, running, playing sport or just trying to stay fit for longer.
“If you’re choosing between another scoop of protein powder or adding more beans, lentils, nuts, seeds and vegetables to your diet, the latter is often where you’ll see the greatest benefit for your overall health
Add fermented foods to your diet
“Adding fermented foods is another habit that is backed by science. Foods such as kefir, kimchi, sauerkraut can introduce beneficial microbes and, when combined with a fibre-rich diet, help support a healthier gut environment. Research has shown that increasing fermented food intake can improve microbiome diversity and reduce markers of inflammation.”
